Manchester City's ?100m man has sparked speculation online after he was spotted using exclusive celebrity dating app Raya just hours after the defeat at Tottenham at the weekend.
The 25 year old, who is currently in a relationship with model Sasha Attwood, also 25, wrote on his supposed profile: ?Visiting London . . . from Birmingham.'
In a duo of screenshots published by The Sun, a profile on the site shows the footballer on a private jet while another photo is of him posing in a Louis Vuitton jacket from a shoot with Sports World.
Jack has previously shown his admiration for former Love Island contestants, after he was caught hitting on reality star Natalia Zoppa, 22, by her boyfriend
Raya is an ultra-exclusive private dating app which describes itself as ?online membership for dating, networking, and making new friends', where users must go through an exhaustive application process before joining.
A spokesperson for the star told the MailOnline: ?We don't comment on these matters, whether they are correct or incorrect.'
The news comes after Jack liked a series of Love Island contestant Lillie Haynes' raunchy bikini pictures on Instagram ? before then suddenly removing the interaction days later.
A source told MailOnline: ?Lillie couldn't believe Jack even knows who she is, let alone took the time to like her uploads on Instagram.
Jack liked a photo of Lillie in a bikini that was shared while she was in Casa Amor on the 26th of July, along with a snap of the reality star enjoying a glass of bubbles to celebrate her ?freedom' after returning from Mallorca and quarantining for five days.
But now it would seem he isn't interested no more, and has now turned to Raya in order to find someone else to spark his attention, yet as widely publicised, he's said to be in a relationship with Sasha Attwood, who often watches him in action from the stands.
In April, Jack joked during an interview alongside ex-Villa teammate John McGinn that he'd be ?on Love Island or working as a promotor or DJ' if he failed as a joingy-login sportsman.
He also shared an image of himself and his fellow England teammates watching Love Island on a large screen in a communal room inside the team's Euro hotel last month and joked that dumped Islander Hugo Hammond looked like the spit of defender Ben White.
In a video shared on TikTok, the 2020 Islander Natalia's partner Hass Saleh claimed: ?As if today couldn't get any weirder, the best player in the Premier League tried to chat up missus,' while sharing the alleged Instagram message from Jack, a waving emoji.
Recently, Grealish admitted he's a ?big fan' of Love Island, even saying if he wasn't a footballer, he'd be a contestant on the ITV2 show
It was reported in June that Jack and his childhood sweetheart Sasha had got back together after a brief split, and he considered the model his ?secret weapon' off the pitch.
The couple, who were pictured on holiday together in Croatia last month, met while they were teenagers at St Peter's Roman Catholic Secondary School in Solihull.
Social media users reacted as Jack Grealish is apparently caught ?playing away' on a dating app and likes another Love Island star's raunchy pics...
tilly123: She loves the money and lifestyle she will be hanging on for grim life. Jack loves partying and women and is well known for both. Same old story as Colleen, John Terrys wife, Kyle Walkers mrs, VB, RFs poor wife, the list goes on and on, typical premier league couple
Dylan The Dawg: What the Hell does Sasha see in this GBP 100 Miilion record transfer loser it just baffles me?
JayMa: Money really can't buy class. When it all goes wrong he`ll be back at Villa Park knocking the front door.
NikNak76: I find it strange that he spent the whole summer at the Euro's, then when it's finally over he decides the first thing to do is go to Mykonos with his mates. Instead of being with his girlfriend. He obviously missed her very much. Not. Then when they were in Croatia the pics looks like they were mates. I just think his relationship with Sasha is a bit strange.
Yetunde: He needs to do the right thing by this woman and set her free. He's not going to be faithful or he's going to have her hanging on for years before unceremoniously dumping her.
Anon68230: He'll buy his Mrs a new bag and all will be forgotten. She's a doormat for staying with him. Every Villa fan knows exactly what Jack is like. He's been this way for years and his Mrs hasn't batted an eyelid...
kismet2020: Well, what a surprise an overpriced, over rated footballer who's only actual talent is that he can't keep it in his pants.
